WATER HEATER.

Application filed July 8,

This invention relates to a water heater for furnaces.

The object of the invention is to provide a heater of this characterwhich is adapted to be removably mounted in a furnace and which isadjustable to be positioned in the hottest part of the fire withoutinterfering with firing since it can be easily withdrawn for thispurpose.

Another object is to provide a heater of this character which iscontrollable for varying the amount and the intensity of the heat of thewater heated thereby.

Another object is to provide a Water heater of this character which maybe easily replaced at any time with minimum trouble and expense shouldit become clogged with lime or sediment deposited by the water.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the in vention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 represents a side elevation of afurnace with this improved heater shown applied, parts being broken outof the furnace to show the location of the heater within it; and

Figure 2 is a detail rearelevation of the heater shown in operativeposition.

In the embodiment illustrated, the heater constituting this inventioncomprises a hollow casting 1 here shown rectangular in form and which isdesigned to be inserted in the fire box of a furnace shown at F. Thishollow casting 1 has a horizontal partition 2 extending longitudinallythereof from its rear toward its front end and terminating short of saidfront end to afford communication between the space at the top and atthe bottom of the partition as is shown clearly in Figure 1.

The upper chamber 3 is connected by a flexible rubber hose 10 to theupper portion of a hot water tank T while the lower compartment a isconnected by a similar hose 11 with the lower end of said tank. Asuitable handle is provided at the rear end of the casting so that thecasting may be conveniently thrust into the fire box of the boiler orfurnace or withdrawn therefrom according to the amount of hot waterdesired and the position in which it is desired to locate the heater.

A suitable slot is provided in the fire box of the furnace through whichthe casting may be inserted.

The casting being flexibly connected with the hot water tank T by a flowand return pipe shown at 11 and respectively, said casting being free toslide in and out through the slot in the furnace, it will be seen thatany degree of heating capacity may be obtained by adjusting the positionof the cast ing to any point desired.

When a large quantity of hot water is desired or hot water is Wantedquickly the casting is pushed all the way into the fire box while for amoderate amount it is pulled say half way out, or if the tank is too hotand the water starts to boil it may be pulled all the way out. I

This removable heater overcomes the ob jection of a permanently set coilin that it can be positioned in the hottest part of the fire box andwill not interfere with firing as it can be easily Withdrawn beforestarting the fire and thus be entirely out of the way.

The pipes leading to the upper'and lower ends respectively of the tank Tare equipped with gate valves 12 and 13 having couplin for connection ofthe hose 10 and 11. Should the heater become clogged with lime orsediment deposited by the water it may be easily removed and replaced byanother by simply Serial No. 42,256.

unscrewing the hose 10 and 11 from the valve carried pipes which leadto, the tank, it of course being understood that the-valves 12 and 13are first closed. After-the new heater,

has been substituted the valves are again opened and the device is readyfor use. This change can be made in a few minutes by any inexperiencedperson thus avoiding the necessity of expensive plumbing work inaddition to making the change at the time desired.

I claim In a device of the class described, a furnace having an opening,a. water heater prothat the heater may he slid by means of the 1 jettinginto the furnace through the openhandle entirely out of the opening andfree mg: the heater having a free, slidable, from the furnace, and heslid for adjustment metal-to-metal-contast mounting in the opento varythe amount that the heater projects 5 ing, the heater having flexiblewater-supply into the furnace.

connections, the heater being provided at its In testimony that I claimthe foregoing 1i outer end with a hand-grip, the cross secas .my own, Ihave hereto eflixed my slgnationai contour of the heater bearing suchreture. lation to the size and shape of the opening FELIX J. MCGUANE.
